Oil (SG=0.82) entering a pump through an 8-inch diameter pipe at 4 psi has a flow rate of 3.5 cfs. It leaves the pump through a 4-inch diameter pipe at 15 psi. Assuming that the suction and discharge sides of the pump are at the same elevation, find the horsepower delivered to the water by the pump (550 lb.ft/s = 1 HP). Illustrate the problem and show your complete solution.
b. The discharge pressure of an air compressor is 6 times the suction pressure. If the volumeflow rate at the suction is 0.86 cubic meters per second, what is the compressor power (kW)for n = 1.38 and suction pressure is 101 kPaa?
Seven hundred gpm of water are being discharged by a centrifugal pump 5 ft. above the pump inlet. The inlet pressure is 4-in Hg above atmospheric and the discharge pressure is 29 psia. Assume the pump input is 8 hp, if the pump has an 8-inch diameter inlet and a 4-inch diameter discharge:
